About this file

This document is a Specifications List for a Neutron Generator Repair Contract for the Adelphi DT-108-API associated particle neutron generator owned by NSDL. The repair specifications include replacing the API window and YAP scintillator due to a slow leak caused by a cracked weld on the viewport. Required services encompass replacement of the viewport, scintillator crystal, and scintillator holder, safe disposal of tritium-contaminated parts, potential 0.8-micron foil replacement, helium leak checking, and a basic function test to verify plasma and neutron generation. The contract requires calibration documentation and leak testing certifications per NRC guidelines, with a 3-month warranty on parts provided by the service provider.

Adelphi Neutron Generator Repair

Specifications List for Contract:

• Replacement of API window and scintillator

• The Adelphi DT-108-API associated particle neutron generator currently owned and operated by NSDL has developed a slow leak due to a crack in a weld on the viewport where the getter circuit and YAP scintillator are located. An attempt to repair using VacSeal was unsuccessful, and the YAP scintillator was damaged.

• Repairs will consist of the replacement of the viewport and YAP scintillator (customer supplied), pressurization and operating tests to confirm the device holds pressure per operating specifications. Calibration documentation and leak testing certifications per NRC guidelines are to be provided.

• Repair for Adelphi DT-108-API, leakage detected due to cracked weld housing

• Replacement of viewport, scintillator crystal, and scintillator holder

• Safe disposal of tritium contaminated parts

• Removal and replacement of 0.8-micron foil installed below the scintillator crystal if necessary

• Helium leak check of the system and I can perform

• Basic function test to make sure the plasma lights and it can make neutrons

• 3-month warranty on parts
